中草药添加剂对生长育肥猪生长性能的影响研究

Effect of Chinese Herb Feed Additives on the Growing Characteristics in Growing and Finishing Pigs

选用 2 0kg左右的“杜长大”三元杂交猪 16 0头 ,分成对照组、中药组、中药 +西药组、西药组 4组 ,每组 4个重复。分 2 0～ 30kg ,30～ 70kg ,70～ 110kg三个阶段的饲养试验 ,并统计分析全程饲养试验结果。结果表明 :添加中草药添加剂 ,能明显改善生长育肥猪的生长性能和饲料利用效率 ,在 2 0～ 30kg ,30～ 70kg ,70～ 110kg以及全程 (2 0～110kg)饲养试验中 ,日增重分别比对照组提高 9 2 8% (P <0 0 5 ) ,1 70 % (P >0 0 5 ) ,13 6 9% (P <0 0 5 )和 7 4 4 % (P<0 0 5 ) ;料重比分别比对照组降低了 4 4 4 % (P >0 0 5 ) ,9 77% (P <0 0 5 ) ,11 6 3% (P <0 0 5 )和 13 6 5 % (P <0 0 5 ) ,并能有效防止 2 0～ 30kg仔猪发生腹泻。结果还显示 ,添加提取的中草药有效成分 ,对生长育肥猪的促生长效果 ,与添加抗生素和 (或 )化学合成药物的相当 。

Experiment has been conducted to investigate the effect of feed additives of Chinese herb on the growing characteristics in piglets through feeding.160 growing and finishing pigs (Duroc×Landrace×Yorkshire,20kg initially)were assigned into control and treatment group set with four replicate pens per treatment by weight and sex. Fed basic diet supplemented with Effective Components of Chinese Medicinal Herbs (ECCMH) or antibiotic chemical compound drug. The results showed that ECCMH can remarkably improve the growth characteristics and FCR in growing and finishing pigs. Comparing with the control group, ADG was increased by 9.28% ( P <0.05), 1.70% ( P >0.05), 13.69% ( P <0.05) and 7.44%( P <0.05); FCR was decreased by 4.44% ( P >0.05), 9.77%( P <0.05), 11.63%( P <0.05) and 13.65%( P <0.05) during the growing period of 20～30?kg, 30～70?kg, 70～110?kg and 20～110kg respectively. The frequency of diarrhea of piglets was decreased remarkably. These results also indicated that the ECCMH could substitute antibiotic/or chemical compound drug for improving the growing characteristics in growing and finishing pigs.
